Abstract: Separate stripping (14) and rectifying (16) sections are arranged in tandem, each section being segregated into a plurality of vapor liquid contact stages (24-32, 34-42). The rectifying section (16) is operated at a higher temperature than the stripping section (14) by compressing (66) vapor from the stripping section (14) prior to introducing the vapor into the rectifying section (16). Thermal energy is conserved during the distillation process by transferring thermal energy from the rectifying section (16) to the stripping section (14) with a plurality of heat pipes (84-87).

Abstract: Gang saws and other cutting apparatus having oscillating cutters for cutting workpieces into slices. The apparatus has two elongate spaced apart cutter supports (12, 13) which are driven to oscillate 180° out of phase with each other. Two sets of cutters (11) are connected to the supports. For a suitable workpiece the cutters may be of a hot wire type. Each cutter (32) of one set (11) is connected to the first support (13,47) by a resiliently extensible connector such as a spring (34) and to the second support (12, 47) by a non-extensible connection. Each cutter (32) of the other set (11) is connected to the second support (12, 47) by a resiliently extensible connector (35) and to the first support (13,47) by a non-extensible connection. Desirably the cutters of one set alternate with cutters of the other and all cutters are coplanar. Movement of cutters of each set in opposite directions tends to cancel the local influence of cutters on the workpiece. Moreover whole frames of cutters may be removed and replaced, facilitating reprogramming of the apparatus in terms of spacings between cutters.

Abstract: In einem Verfahren zum Aufwickeln von textilen Fäden mit konstanter Geschwindigkeit zu wildgewickelten Kreuzspulen wird die sogenannte Atmung angewendet, um harte und verdickte Spulenenden zu vermeiden. Dabei wird in einem Atmungszyklus (TA) die Changierhublänge (HCH) gegenüber ihrem Maximalwert (HCHmax) (= Wikkellänge) wiederkehrend zeitweilig auf einen zwischen diesem Maximalwert (HCHmax) und einem festgelegten Minimalwert (HCHmin) liegenden Wert in einem Verkürzungstakt (TK) verkürzt, in einem Verlängerungstakt (TL) wieder auf den Maximalwert (HCHmax) verlängert und in einem Ruhetakt unverändert beibehalten. Die als Atmungshub (ΔA) bezeichnete Differenz zwischen der Maximalhublänge (HCHmax) und der kürzesten Changierhublänge eines Atmungszyklus (TA) wird während der Herstellung eines kompletten Spulenwickels mehrfach verandert beispielsweise nicht-periodisch nach einer Zufallszahlenfolge. Parallel zur Atmung kann zum Zwecke der an sich bekannten Spiegelstörung die Changiergeschwindigkeit (VS) des Changierfadenführers zwischen vorbestimmter Maximal- und Minimalgeschwindigkeit ständig abwechselnd beschleunigt und verzögert werden. Atmung und Spiegelstörung können zeitlich derart aufeinander abgestimmt sein, daß die Zeitpunkte kurzer Changierhublängen mit Zeitpunkten hoher Changiergeschwindigkeiten - und umgekehrt - zusammenfallen.
